4. Array (2) Advanced Applications and Characters and Character Arrays 1. Array-table-driven method-bool type Table-driven method is also called table-driven and table-driven method. “Table” is a very useful data structure that is discussed in almost all data structure textbooks. The table-driven approach is a method that allows you to look up information in a table […]

Exclusive and original! The sparrow optimization algorithm that combines northern goshawk and adaptive t distribution has excellent results! Highly recommended product! MATLAB code…
Statement: Resale and reselling of the author’s original code is prohibited, and violators will be prosecuted! The sparrow search algorithm (SSA) was proposed in 2020 and has been widely used in many fields. The design of the Sparrow algorithm is inspired by the biological characteristics of birds. The mathematical model established based on the foraging […]
Construct an array object using a sequence of bytes
“How are arrays in .NET laid out in memory? 》Introduces a memory layout for array objects under .NET. Now that we know the memory layout, we can naturally create a byte sequence to represent an array object according to this layout rule, just like “Draw an object in memory in pure binary form” to construct […]

[Python Ocean Topic 36] Correlation coefficient of two one-dimensional arrays–preparing for the ocean index
[Python Ocean Topic 36] Correlation coefficient of two one-dimensional arrays – preparing for the ocean index Two sets of data: x = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] A = [41, 63, 83, 71, 94, 62, 60, 42, 55, 67] B = [10, 16, 26, 29, 20, 9, 8, 13, 18, […]
PHP uses recursion to integrate its two-dimensional array into a hierarchical tree, where the hierarchical id is in a uuid format. The weird problem has been solved.
No more verbosity, just go directly to the source code. <?php function findChildren($list, $p_id){ $r = array(); foreach ($list as $k => $item) { if ($item[‘fid’] == $p_id) { unset($list[$k]); $length = count($r); $r[$length] = $item; if ($t = findChildren($list, $item[‘id’])) { $r[$length][‘children’] = $t; } } } return $r; } function findChildren2($list,$p_id, & amp;$sike=[]) […]

How to pack multiple object arrays into Xml (C#, bpel)
Nothing happened these past two days. I took a look at the code of my senior and found that he wrote a more interesting code. I will analyze and record it here. 1. Situation analysis There are five pieces of data in the picture above. To transmit these five pieces of data to the backend, […]
C language pointer array pointer traversal
Pointer array pointer traversal Refer to the summary of knowledge about C language novices turning into monsters 1. All data in the computer must be put into memory, and different types of data occupy different spaces, such as int 4 bytes char 1 byte 2. Pointer (address): Each byte in memory has its own address, […]
System.arraycopy for array copy
In order to test the difference between the two, I wrote a simple program that assigns int[100000] for comparison, and used nanoTime to calculate the time difference: The procedure is as follows: int[] a = new int[100000]; for(int i=0;i<a.length;i + + ){ a[i] = i; } int[] b = new int[100000]; int[] c = new […]
